When two plates move apart, the weaker part of Earth's crust moves down at normal faults where sediments are. deposited until a basin forms. At the area where two bent plates slide past each other, a depression forms where sediments are deposited.
past each other, a depression forms where sediments are deposited. When two plates collide, the non-subducting plate scrapes the subducting plate and forms a depression where sediments gather.
